Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]] Options: --nosetuid -n This program generally tries to setuid `nobody', unless this flag is set. The setuid call will fail if this program is not run as root (in which case, use this flag). --version -V Print the version number and exit. --class classname -c classname Use `classname' as the concrete SMTP proxy class. Uses `PureProxy' by default. --debug -d Turn on debugging prints. --help -h Print this message and exit. Version: %(__version__)s If localhost is not given then `localhost' is used, and if localport is not given then 8025 is used. If remotehost is not given then `localhost' is used, and if remoteport is not given, then 25 is used. iNt SMTPServert DebuggingServert PureProxyt MailmanProxyi s Python SMTP proxy version 0.2t Devnullc B s e Z d Z d Z RS( c C s d S( N( ( t selft msg( ( s /usr/lib64/python2.7/smtpd.pyt writeX s c C s d S( N( ( R ( ( s /usr/lib64/python2.7/smtpd.pyt flushY s ( t __name__t __module__R R ( ( ( s /usr/lib64/python2.7/smtpd.pyR W s s t s , c C s; t j t t IJ| r* t j | IJn t j | d S( N( t syst stderrt __doc__t globalst exit( t codeR ( ( s /usr/lib64/python2.7/smtpd.pyt usageb s t SMTPChannelc B s e Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z RS( i i c C s t j j | | | | _ | | _ | | _ g | _ | j | _ d | _ d | _ g | _ d | _ t j | _ y | j | _ Wn: t j k r } | j | d t j k r n d SXt d It | j IJ| j d | j t f | j d d S( Ni R s Peer:s 220 %s %ss ( t asynchatt async_chatt __init__t _SMTPChannel__servert _SMTPChannel__connt _SMTPChannel__addrt _SMTPChannel__linet COMMANDt _SMTPChannel__statet _SMTPChannel__greetingt Nonet _SMTPChannel__mailfromt _SMTPChannel__rcpttost _SMTPChannel__datat sockett getfqdnt _SMTPChannel__fqdnt getpeernamet _SMTPChannel__peert errort closet errnot ENOTCONNt DEBUGSTREAMt reprt pusht __version__t set_terminator( R t servert connt addrt err( ( s /usr/lib64/python2.7/smtpd.pyR m s* c C s t j j | | d d S( Ns ( R R R- ( R R ( ( s /usr/lib64/python2.7/smtpd.pyR- s c C s | j j | d S( N( R t append( R t data( ( s /usr/lib64/python2.7/smtpd.pyt collect_incoming_data s c C s t j | j } t d It | IJg | _ | j | j k r | sZ | j d d Sd } | j d } | d k r | j } d } n$ | | j } | | d j } t | d | d } | s | j d | d S| | d S| j | j k r| j d d Sg } xN | j d D]= } | r\| d d k r\| j | d q,| j | q,Wt j | | _ | j j | j | j | j | j } g | _ d | _ | j | _ | j d | s| j d n | j | d S( Ns Data:s 500 Error: bad syntaxt i i t smtp_s' 502 Error: command "%s" not implementeds 451 Internal confusions t .s 250 Ok( t EMPTYSTRINGt joinR R+ R, R R R- R t findt uppert stript getattrt DATAt splitR4 t NEWLINER!

It has been `de-transparencied' according to RFC 821, Section 4.5.2. In other words, a line containing a `.' followed by other text has had the leading dot removed. This function should return None, for a normal `250 Ok' response; otherwise it returns the desired response string in RFC 821 format.
